conforce.tensor_util

This module contains methods to work with first-order tensors (vector) and second-order tensors.

Functions

abaqus_notation_from_tensor(tensor, dim_vector)	Convert tensors into the abaqus notation.
do_rotation_tensor(ROT, tensors)	Rotate second-order tensors using rotation matrices.
do_rotation_vector(ROT, vectors)	Rotate vectors using rotation matrices.
rotation_matrix_from_quaternion(Q)	Create rotation matrices out of quaternions.
tensor_from_abaqus_notation(array)	Convert a second-order tensor from the abaqus notation into the matrix form.
undo_rotation_tensor(ROT, rotated_tensors)	Revert the rotation of second-order tensors done by rotation matrices.
undo_rotation_vector(ROT, rotated_vectors)	Revert the rotation of vectors done by the given rotation matrices.
